My BD wants DD to stay over at his house with him and his family, he has met her about 7 times and didn't come into her life until she was 5 months old due to walking out on us and not being ready to be a dad, his family have met her twice for a few hours, he lives two hours away, he has told me I either let her stay over or he's taking me to court. He keeps talking to me saying we are a family and he only wants the fairness. but then threatens me with court all the time.
